GENUS STRUMIGENYS FR. SMITH : GROUP OF 
S. GODEFFROYI IN BORNEO 1

This paper is a further contribution in a series which, 
when complete, will cover the known species of the Indo- 
Australian portion of the dacetine ant genus Strumigenys 
Fr. Smith. For general background, explanations of ab- 
breviations used in citing measurements and indices, and 
discussion of S. godeffroyi Mayr and related species, see 
Brown, 1949, Mushi 20 : especially pp. 2 and 16-19. Previous 
parts of this series, the first two of which also include ex- 
planations of abbreviations for measurements, etc., are in 
Psyche 60: 85-89 (1953), 60: 160-166 (1954), 61: 68-73 
(1954), 63: 113-118 (1956), and 64: 109-114 (1957). Fig- 
ures of these species have been prepared, but are being saved 
for use in collective plates in connection with the eventual 
keys to all the Indo-Australian species of the genus. 
I have seen a dealate female of 5. godeffroyi Mayr from 
Long Navang, northern Borneo, E. Mjoberg leg- This spe- 
cies probably occurs at many coastal points and around 
settlements inland. It is widespread in the tropics of south- 
eastern Asia and the Pacific. 
The following five species evidently are much more local 
and rare. 
Strumigenys dyak sp. nov. 
Holotype worker: TL 3.07, HL 0.80. ML 0.35, WL 0.80 mm.; 
Cl 69, ML 44. Close to S. solifontis Brown, from Japan, but 
differing chiefly in the shorter and straighter mandibles, 
and in the long preapical tooth being set only a little more 
than half its own length away from the dorsal apical tooth. 
The size, proportions of the head, and shape of alitrunk are
